Embodiment 1

[0053] Example 1: 20% neem element. Imidacloprid wettable powder

[0054] Neem 8% (weight);

[0055] Imidacloprid 12% (weight);

[0056] Wetting agent: sodium lauryl sulfate 10% by weight;

[0057] Dispersant: 10% (weight) of alkyl sulfonate;

[0058] Filler: Kaolin is 40% (by weight);

[0059] Diatomaceous earth is 20% (weight);

[0060] After each component is dried, cooled and mixed, it is pulverized by airflow until 95% of the pulverized product passes through a 325-mesh sieve to obtain 20% nimbin. Imidacloprid wettable powder.

Embodiment 2

[0061] Example 2: 10% neemin. The preparation of imidacloprid emulsifiable concentrate, each component distribution ratio is:

[0062] Neem 4% (weight);

[0063] Imidacloprid 6% (weight);

[0064] Surfactant: dodecylphenol polyoxyethylene ether is 12% (weight);

[0065] Organic solvent: 25% (by weight) each of N,N-dimethylformamide and xylene;

[0066] Cosolvent: ethyl acetate is 15% (weight);

[0067] Anti-photolysis agent: castor oil is 1% (weight);

[0068] Penetrant: laurocaprazine is 12% (weight);

[0069] First dissolve a quiet amount of imidacloprid with N,N-dimethylformamide, then dissolve nimbin with xylene, then mix the two solvents evenly, and then put in quantitative emulsifier, anti-light solution agent, penetrant, etc., stir evenly, settle and filter to remove mechanical impurities, that is, the product.

Embodiment 3

[0070] Example three: 20% neem element. The preparation of imidacloprid suspension concentrate, each component distribution ratio is:

[0071] Neem 8% (weight);

[0072] Imidacloprid 12% (weight);

[0073] Dispersant: sodium lignosulfonate is 15% (weight);

[0074] Tackifier: bentonite is 5% (weight);

[0075] Stabilizer: xanthan gum is 5% (by weight);

[0076] Antifoaming agent: organosilicone is 3% (weight);

[0077] Solvent: castor oil is 52% (weight);

[0078] The above-mentioned neemin and imidacloprid binary insecticidal composition has dual effects of contact killing and stomach poisoning, and can be widely used in the prevention and control of Lepidoptera and Homoptera pests on various crops. disease showed high efficacy.

[0079] 2. Application of nimbin and imidacloprid binary insecticidal composition

Abstract

The invention belongs to the technical field of biopesticides and particularly relates to a biological compound insecticide containing toosedarin and imidacloprid and a preparation method and application thereof. The biological compound insecticide provided by the invention comprises the following components: 1-40 percent of toosedarin, 1-40 percent of imidacloprid and the balance of addition agents. The biological compound insecticide containing the toosedarin and the imidacloprid is remarkable in synergism, has a high pesticide effect, a good fast-acting property and a wide insecticidal spectrum, is capable of delaying the generation of drug resistance, and has the advantages of convenience in use as well as safety and reliability.

Description

1. Technical field [0001] The invention belongs to the technical field of biopesticides, and in particular relates to a biocomposite insecticide of nimbin and imidacloprid, a preparation method and application thereof. 2. Background technology [0002] During the growth and development of crops, they are vulnerable to various pests, especially vegetable crops, which have a wide variety of pests and serious damage, such as aphids, diamondback moths, and cabbage caterpillars. For a long time, chemical control has been the main control method of crop pests, that is, the application of chemical pesticides. However, with the long-term use of chemical pesticides, pests are prone to develop drug resistance, resulting in a decline in the control effect, and the frequent use of chemical pesticides damages the ecological environment. and threaten human health, so that the biological control of pests has attracted more and more attention. However, compared with chemical insecticides...
